The DVD set features standalone episodes of Head Rush and 4 "episodes" of MythBusters, which are actually re-cut edits of older myths interleaved with Head Rush segments--think "Head Rush commercials". The Head Rush segments themselves are fun, entertaining, and even informative for all ages despite being aimed mainly at a younger audience. THe MythBusters episodes might contain previously unseen footage depending on what cut was aired in your region. The DVD production is OK--the menus seems little wonky and relative speaking it looks quite low-res, albeit some of the footage is actually quite old now and it shows.Overall, this Head Rush set is entertaining, and as one promo I saw said, "More Kari!"
